` V a citizen of the Unitedv States, Aand a resifeo t. showing the .,40

j'new and useful Hub bearing for dent of Terre Haute, county of Vigo, and

State of Indiana,V haveinvented a certain Structure for Roller- Bearingsaud I do hereby declare that the following 1s a full, clear, and exact descrip- .tion thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

This invention relates to bearing structures for wheel hubs, 'journal boxes, pillow blocks and the like and e, feature of the invention is the revision of means for holdn tion 1s the provision oi means orgorcventing the lubricant from .leaving the bearing after once being introduced thereintd A further feature of the invention is the vprovision of means for introducing lubricant into the bearing. A further feature off the invention is the provision of a closingmeans for the ends of the hub or bearing, and` a further feature of the invention is the provision of a reservoir within the hub or the reception of lubricant.

The full nature of the invention Will be understood 'from 4the accompanying; drawings and the following description. and

claims.

Figure 1 is a side elevation of a Wlurel, hub, axle andbearing therefor 1n section, said sectlon being on hue Imi oi Fig. 2. Fig.- 2 is a sectionalview as seen on Fig. 1; Fig. i3 is a sectional ers iective vlew of a. lloushnw used in conf lar reference numeral nection with the bearing mechanism. Fig. 4 lis a perspective View of a pillow block showingl the manner of applying the bearing` structure thereto.

Referring to tlrebdrawings in'whch simi s designate corresponding parts throughoutt 'e several views, 1 indientes a wheel Whiohnlay be constructed in any'preferred manner, but.l in the present instance of that class used in connection with mine oars, trucks andthe like and 2 indicates the hub thereof, said hub having a central. bore 3 through which extends an axle 4. In

7 which project inwardly between the ends` of the bearing rollers.

In order to adapt the bearing for use in connection with hubs having bores of Varying diameters, a casing is provided for the bearing rollers and retainer members comprising bushings 8 which are preferably arranged in pairs, the outer ends of the bush ings having; inwardly extending integral Hongos 9 which foi-rn closures for the ends of the bushiigs and when the bushings are introduced into the hub, the bearing rollers and retaining members are entirely inclosed.

The interior oi the hub 2 provided at its lollgitudinai center with a peripheral channel l() whi'crh forms a reservoir for lu l'uicant and by so constructing the bilshings that when properly introduced into the huh, they will remain slightly spared apart at their inner ends, u. narrfw.' ii'erd opening il is provided through which, t. lubricant may pass from the channel lll into engagement with the bearing rollers 5.

-ilhou the lubrimnt enters the bushings 8 the ilanire E) at the ends thereof Will non molly prevent the lubricant from leaving the bearing; at the ends of the hub, but to fully guard against any oil being fra'friedl vout of the hub along the :isle i, a fabric washer 'l2 oli :my suitable ina `erial, is introduced around the axle and pressed against the outer face of the `flange J so that should any small particles oi the lubricant .be carried out of the bushing;y by the. axle, the Washers iii), at the ends of the` bushing Will absorb such lubricant.

The closed ends of the bushings 8 ilrelierg ably project inwardly beyond tho'emls of the huh a sullieient distance to pfeift e a .space ior the .reception of the Washers 12 and faces of the yretainer mern'bers 6, rest, when fifi assembled in the bushing. In addition to forming a very smell bearinr surface for the members 6, said ribs 15 ho d. the retaiin` ing members so spaced :is to forni pockets into swhich lubricant will be deposited and furnish ii constant, lubricant tlieriflor.

Instead, lmwever, olf 'liom'nil'ig the ribs es shown any suitable menus may be provided for engagement with the retaining members. The hub E?, is provided at :i suitable point with a port 16 through which lnbrionnt maybe introduced into the channel ll), any snitable form of closure being provided for the port, suoli. es n. sore-,n.17

In Fig. fl of the drawing the insuring means is shown applied. to a pillow bleek 18 through which entends shaft 1,9 and in stead of providing u emp for ezieli end of the block, having e lionne ior engegement with the outer snrinoe of the. bloeit, nietes 20 ning-1 be introduced over the ends ol ilu l( sind secured thereto by menne nl sere Althjnrh hut two ornieseonrii'xg ihn eoiferiiig :n of ille lnil or bloei-f i: that any suitnlj which Will eee-on find be secured. to the linb in nf.' suir-(ilfle manner. This form oi' device primarily adapted for use in Connect-lob with terni machinery, mine ears, wagons, 'jenn-nal boxes7 pulley bloelrs and the like and also in Connection with idle gp'iilli-fyswhich receive a greet dealer weer nin/.l the prime feature of the invention the eheapness et Whieh it een be produced und. t the seine time give entirely satisfactory i lts..

It will be Clearly understood. that by iucreasing 'the si' o' le lies-ning rollers and likewise the i il. bnsl'iings., a Wheel haring e. huh or of inneh grenier di enieter than :lie of 2 axle shaft in nim Wh" it 'to he mounted. n be readily zweonnnodated, and oniusoi 'to properly fit sronnd the axle 1n assembling the parts of 'the bea-ring structure,I one of the bnsning's is intro-- duced into the hub nieznbei.' and one of the retaining members `then'introduced into the hub and sind bushing, one end of the rollers then engaged with seid. retaining inei'nber and the other retzrinng member then engaged. with the-opposite ends of the rollers and, 'the oppor-Site bushing then positioned in the hub. When the parts ere so semi; ed it will be impossible for the rollt-.rs to become disengaged from the retziii'iing :tiembre-rs. The Washers L2 are then introi'lueed into plee/o and the oeps 13 then introduced over ends of the hub and vse onred thereto. The" ,le then introduced over 'the axle or. snob other hearing with which the seine may?. he used..

The invention claimed is:

l. The combination with a hub structure, n plurality of bearing rollers therein, and ineens to spaee the rollers in said hub struc-- ture, oi e lnishing adopted to be introduced .in eneh end of the hub structure between the hub nnrl seid hearing rollers, the inner ends ol' said bushings being spaced apart to 'forni :in opening, inwardly extendingJ flanges :it the outer ends of the l'nisliing. and ineens engaging the ends ol? the hub for closing the ends thereof.
